We're dividing 983945 by 53 
The aim is to understand the frequency of 53 in 983945.

Step 1:
If we divide 9 by 53, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (8) from the dividend to 9 and continue with: 98 / 53

Let's proceed to step 2:
53 goes into 98 1 times with a remainder of 45.
The next digit of our result is 1. 
Result so far: 1.0
If we take 53 away from 98, we end up with 45.
Append the next digit (3) from the dividend to 45 and continue with: 453 / 53

Advancing to step 3:
453 divided by 53 is 8 with a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we subtract 424 from 453, we get 29.
Take the next digit (9) from the dividend and append it to 29, then repeat: 299 / 53

Going ahead to step 4:
53 goes into 299 5 times with a remainder of 34.
Use 5 as the next digit of our solution. 
Result so far: 185.0
If we take 265 away from 299, we end up with 34.
Fetch the next digit (4) from the dividend, attach it to 34 and continue: 344 / 53

On to step 5:
53 goes into 344 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 1856.0
Subtracting 318 from 344 leaves us with 26.
Take the next digit (5) from the dividend and append it to 26, then repeat: 265 / 53

Moving on to step 6:
If we divide 265 by 53, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 18565.0
If we take 265 away from 265, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
53 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 18565.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
The number 53 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 18565.0
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 18565.0, with a leftover of 0.0.
